Abstract
The utility model discloses a transducer dedicated electric power cable relating to the cable technical field. Three groups of neutral cores and three groups of power cores are positioned in a taped covering layer; each group of the neutral core is composed of a neutral conductor and a first insulating layer; the neutral conductor is arranged in the first insulating layer; each group of power cores are composed of a conductor and a second insulating layer; the conductor is arranged in the second insulating layer. The taped covering layer is arranged in a weave shielding layer, the weave shielding layer is arranged in a copper shielding layer, and the copper shielding layer is arranged in a jacket. The utility model realizes the target of strong interference resistance capability.
Description
Technical field
The utility model relates to the technical field of cable.
Background technology
Along with the development of social life, also more and more higher to the instructions for use of electric power.For the fail safe that increases electric power and use, frequency converter is by a large amount of uses.At present the Frequency Converter Control system is provided the cable of electric power, can not well eliminate the imbalance between the voltage, produce powerful electromagnetic wave, even occur the danger that cable is punctured by high order harmonic component sometimes.Under frequency conversion variation situation greatly, can be subjected to the interference of electromagnetism, influence the stable operation of system.
The utility model content
The utility model purpose provides the strong frequency converter special electric power cable of a kind of antijamming capability.
Three groups of neutral cores of the utility model and three groups of power cores are arranged in the wrapped belt, and every group of neutral core is made of the neutral conductor and first insulating barrier, and neutral conductor is arranged in first insulating barrier; Every group of power core is made of the conductor and second insulating barrier, and conductor is arranged in second insulating barrier; Wrapped belt is arranged in the woven shield, and woven shield is arranged in the copper strips screen, and the copper strips screen is arranged in the oversheath.
In the process of making, three neutral cores are evenly arranged in the gap of three power cores and are twisted into cable core, the twining package tape layer is set outside cable core, the periphery of twining package tape is respectively equipped with woven shield, copper strips screen, oversheath.Adopt symmetric form and shielding construction, can eliminate the interference that produces between master core and the zero line and the imbalance of harmonic voltage effectively because lead exchanges effect and symmetrical balance thereof, the maintenance system is stable.Realized the strong purpose of the utility model antijamming capability.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
